Description

CPU cooling system for computer

[0001] The present invention relates to a CPU cooling system for a computer, and more specifically, to a technology for a CPU cooling system for a computer that improves the cooling efficiency of a CPU by allowing heat generated from a CPU to be released to the outside rather than accumulated inside the main body.

[0002] As computer performance advances, the heat generated by the CPU (Central Processing Unit) also increases, becoming a problem. Computer performance is largely determined by the performance of the CPU, and as CPU performance improves, so does the amount of heat generated. As CPU temperature rises, performance degrades and its lifespan shortens. Therefore, no matter how advanced a CPU is, it will struggle to achieve its full potential if it cannot be cooled efficiently. To address this issue, various cooling systems are being applied to CPUs today.

[0003] There are two main methods for cooling a CPU: one that directly cools the CPU itself, and the other that smoothly dissipates the heat generated during the CPU cooling process to the outside of the main body. Direct cooling methods typically involve installing heat sinks on the CPU or using cooling fans in conjunction with the heat sinks. Some high-performance computers also employ cooling methods such as water cooling. The heat released to the surroundings during the CPU cooling process is then dissipated to the outside by a blower or other device installed in the main body.

[0004] However, the reality is that the above-described conventional technologies aren't efficient enough to maintain CPU performance. First, because CPUs have a small surface area, the area of ​​cooling fins that can be installed for direct cooling is inevitably limited. Even if water cooling is also applied, the space available for installing refrigerant pipes to store or pass refrigerant or coolant is also limited.

[0005] In addition, since the heat released to the surroundings in the process of directly cooling the CPU is structured to be trapped inside the main body, and is released to the outside of the main body in a limited manner by the blower installed in the main body, there is a limit to releasing the heat released from the CPU and trapped inside the main body to the outside. Therefore, no matter how good the performance of the device that directly cools the CPU is, the cooling efficiency decreases as the temperature inside the main body gradually increases over time.

[0006] To minimize heat buildup inside the main body, one method is to install as many blowers as possible on the main body case. However, as the capacity or number of blowers increases, the noise generated also increases. In addition, as the area of ​​the ventilation space increases, dust can easily flow into the inside of the main body when the blower is not in operation. Therefore, there is a limit to increasing the capacity of the blower installed on the main body case.

[0007] The present invention is intended to solve the above-mentioned problems, and the purpose of the present invention is to provide a computer CPU cooling system that can improve cooling efficiency by allowing heat generated from a CPU to escape directly to the outside without being trapped and accumulated inside the main body, and that can secure sufficient space for installing a refrigerant pipe in a water-cooling cooling device.

[0008] The present invention, as a technical means for solving the above problem, comprises a cooling unit provided in a CPU to cool the CPU, and a blower pipe configured such that one end faces the cooling unit and the other end is connected to the outside of the main body case, and is configured to directly discharge heat generated in the cooling unit to the outside of the main body.

[0009] In a preferred embodiment of the present invention, the blower pipe may be configured to have an insulating function to minimize heat passing through the blower pipe from being transmitted to the outside.

[0010] In a preferred embodiment of the present invention, the insulation function is characterized in that the blower pipe is configured with an inner wall and an outer wall, and a vacuum layer is provided between the inner wall and the outer wall.

[0011] In a preferred embodiment of the present invention, the blower pipe may be provided with a blower fan to transfer heat generated in the cooling unit to the outside of the main body case.

[0012] In a preferred embodiment of the present invention, the cooling unit is configured such that one side faces the CPU and the other side is provided with heat dissipation fins, and a refrigerant pipe passes between the heat dissipation fins, and a part of the refrigerant pipe may be configured to be arranged along the length direction of the outer surface of the blower pipe.

[0013] In a preferred embodiment of the present invention, a heat dissipation fin may be provided on the outside of the blower pipe at a position that does not overlap with the position where the refrigerant pipe is arranged, so that heat transferred from the refrigerant pipe is discharged to the outside by the heat dissipation fin.

[0014] In a preferred embodiment of the present invention, the cooling unit is configured such that one side faces the CPU and the other side is provided with heat dissipation fins, a refrigerant pipe passes between the heat dissipation fins, and a portion of the refrigerant pipe may be configured to be discharged along the length direction of the inner side of the blower pipe.

[0015] In a preferred embodiment of the present invention, the cooling unit is configured to include a Peltier element and cooling fins so that the heat absorption portion of the Peltier element faces the CPU, and the heat dissipation fins are provided on the heat dissipation portion of the Peltier element and are configured to extend in the other direction of the blower pipe.

[0016] In a preferred embodiment of the present invention, the cooling unit may further be provided with a blow unit configured to inject compressed air in the direction of the cooling unit.

[0017] In a preferred embodiment of the present invention, the blow unit may be composed of a blow fan that sucks in ambient air and blows it, a cyclone that compresses the air supplied from the blow fan, and a nozzle that sprays the compressed air supplied from the cyclone to the cooling unit.

[0018] The computer CPU cooling system according to the present invention has the advantage of improving cooling efficiency because the heat generated from the CPU is quickly dissipated to the outside rather than accumulating inside the main body. Furthermore, in the case where the configuration that directly cools the CPU is water-cooled, there is the advantage of securing sufficient space for installing the refrigerant pipes of the water-cooled cooling device.

[0028] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

[0030] FIG. 1 is a drawing illustrating a state in which a CPU cooling system for a computer according to the present invention is applied to a computer, FIG. 2 is a drawing illustrating a schematic configuration of a CPU cooling system for a computer according to the present invention, FIG. 3 is a drawing illustrating a configuration of a blower pipe (130) according to the present invention, and FIG. 4 is a drawing illustrating a configuration of a CPU cooling system for a computer according to another embodiment of the present invention.

[0031] Referring to FIGS. 1 to 4, it can be seen that the CPU cooling system for a computer according to the present invention is composed of a cooling unit (100) provided in the CPU (10), and a blower pipe (130) configured so that one end faces the cooling unit (100) and the other end is connected to the outside of the main body case (30).

[0032]

[0033] *CPU ((10), CPU; Central Processing Unit) refers to the central processing unit of a computing device such as a computer. The computer CPU cooling system according to the present invention is a technology mainly applied to desktops among personal computers (PCs, Personal Computers). However, it goes without saying that the present invention can be applied to all known devices as long as the computing device can be installed with a blower pipe (130), etc. and is equipped with a CPU (10). The following description will be given using a desktop computer as an example.

[0034]

[0035] The cooling unit (100) includes all known components that directly cool the CPU (10). Most conventional computers also have a cooling unit (100) for directly cooling the CPU (10). The cooling unit (100) includes an air-cooled cooling unit that contacts the CPU (10) on one side and has a heat dissipation fin (110) on the other side, and a water-cooled cooling unit that cools the CPU (10) using a refrigerant or water. The cooling unit (100) referred to in the present invention includes all known CPU (10) cooling devices, except in cases where specifically mentioned additionally.

[0036]

[0037] The blower pipe (130) is configured such that one end faces the cooling unit (100) and the other end is configured in the form of a hollow tube that is connected to the outside of the main body case (30). Here, configuring one end of the blower pipe (130) to face the cooling unit (100) includes not only a form in which it is in complete contact with the cooling unit (100) or a form in which it surrounds and seals the cooling unit (100), but also a form in which it is somewhat spaced apart from the cooling unit (100). In other words, it means any structure that can sufficiently suck in air around the cooling unit (100) by the blower fan (150) to be described later. The blower pipe (130) may be configured to have a polygonal cross-section, but is preferably configured in a cylindrical shape as illustrated in the drawing. Hereinafter, a cylindrical blower pipe (130) will be described as an example. However, the above example does not exclude a blower pipe (130) configured in a polygonal shape. It is desirable for the blower pipe (130) to be configured in a straight line to ensure smooth air flow, but it may of course be configured in a curved shape depending on the conditions of the installation space.

[0038] One end of the blower pipe (130) is configured to be able to suck air in the direction of the cooling unit (100) provided in the CPU (10). Therefore, one end of the cooling unit (100) may be in contact with the CPU (10) or the cooling unit (100) provided in the CPU (10) as described above, or may be in a form that is completely sealed. However, it is preferable that one end of the blower pipe (130) be configured to be spaced apart from the CPU (10) and / or the cooling unit (100) by a certain distance. Thus, one end of the blower pipe (130) is prevented from contacting the motherboard on which the CPU (10) is mounted, and when the blower pipe (130) sucks air around the CPU (10) or the cooling unit (100), the surrounding air can be smoothly supplied in the direction of the cooling unit (100).

[0039] The cooling unit (100) that is mounted on the CPU (10) and directly cools the CPU (10) is mostly equipped with a heat dissipation fin (110). That is, it is common for the heat dissipation fin (110) to be provided as a basic feature not only in the air-cooled type but also in the water-cooled type. Therefore, the cooling unit (100) must be smoothly supplied with relatively low-temperature surrounding air so that the cooling efficiency is improved as the heat dissipation fin (110) cools down. Therefore, it is desirable to have a structure that does not obstruct the supply of surrounding air to the cooling unit (100) by the blower pipe (130).

[0040] The other end of the blower pipe (130) is configured to be connected to the outside of the main body case (30). For example, the blower pipe (130) extending from one end is configured to face a certain part of the main body case (30), and an exhaust hole (not shown) having a shape corresponding to the other end of the blower pipe (130) is formed in the main body case (30) facing the other end of the blower pipe (130) so that the other end of the blower pipe (130) is configured to face the exhaust hole. Thus, air sucked into one end of the blower pipe (130) is not dispersed to the surroundings (inside the main body case) but is discharged to the outside of the main body case (30) through the exhaust hole.

[0041] It is desirable that the exhaust hole provided in the main body case (30) be provided with a mesh or filter to prevent dust or foreign substances from entering the interior of the main body case (30). If the exhaust hole is provided with a mesh or filter, the air flow is partially obstructed, so the blower pipe (130) can be configured to be wider from one end to the other as shown in the drawing so that even if the air flow is partially blocked by the mesh or filter, it can be discharged smoothly.

[0042]

[0043] In a preferred embodiment of the present invention, the blower pipe (130) is preferably provided with an insulating function to prevent or minimize heat passing through the blower pipe (130) from being transferred to the outside in the circumferential direction. The reason why the conventional CPU (10) cooling system is inefficient is not only because the performance of the cooling unit (100) itself is low, but also because the heat generated while cooling the CPU (10) in the cooling unit (100) is not smoothly released to the outside of the main case (30) but is accumulated inside, thereby increasing the temperature of the surrounding air that must cool the CPU (10). The cooling unit (100) absorbs the heat generated during the operation of the CPU (10) and quickly transfers it to the heat dissipation fins (110), and the heat transferred to the heat dissipation fins (110) is released to the surroundings while being cooled by the air. However, the heat released through the heat dissipation fins (110) is trapped inside the main case (30) and increases the temperature around the heat dissipation fins (110). In this way, the inside of the computer body becomes an isolated system, and the heat released when the cooling unit (100) cools the CPU (10) accumulates inside the body, thereby increasing the surrounding temperature. As the surrounding temperature increases, the temperature difference between the cooling unit (100)'s heat dissipation fin (110) and the surrounding temperature gradually decreases, and a state close to thermal equilibrium is reached, so the cooling efficiency by the heat dissipation fin (110) decreases.

[0044] In order to prevent such problems, a ventilation fan is provided in the main body case (30) to discharge the air inside the main body to the outside. However, since the inside of the computer is equipped with various parts and the main body case (30) is mostly closed, it is difficult in reality to sufficiently discharge the heat generated from the CPU (10) to the outside using only the ventilation fan. Therefore, as the time of using the computer increases, the temperature inside the main body gradually increases, resulting in a decrease in cooling efficiency. In particular, in the case of a high-performance computer with a large amount of heat generation, the heat accumulated inside is greater than the heat released to the outside, resulting in a decrease in cooling efficiency as the temperature inside the main body gradually increases over time.

[0045] Some computers try to prevent heat from accumulating inside by increasing the size of the ventilation fan or installing multiple ventilation fans to ventilate a large amount of air. However, as explained above, the main body case (30) is mostly a closed structure and the inside is complexly equipped with components and wires, so there are bound to be blind spots where the airflow is blocked. The more heat accumulates in the blind spots, the higher the internal temperature. In addition, although the cooling efficiency can be improved by increasing the size or number of ventilation fans, another problem arises in that a lot of dust is introduced through the ventilation fans. That is, the passage equipped with the ventilation fan becomes a passage through which dust is introduced when the computer is not in use (when the ventilation fan is not operating). Even when the ventilation fan is operating, outside air must be introduced through another passage in the amount of air exhausted through the ventilation fan, so a large amount of dust is introduced together with the introduced air. If dust enters the computer body and accumulates on the main board or CPU (10), it can cause short circuits or terminals, which can lead to malfunctions or failures. In this way, the computer body has a contradictory purpose of having to ventilate the internal air as much as possible for cooling, but also having to minimize the inflow of external air to prevent the inflow of foreign substances or dust, etc. Therefore, ventilation alone has limitations in sufficiently ventilating the air inside the computer body.

[0046]

[0047] However, if all of the heat generated from the CPU (10) is discharged to the outside through the blower pipe (130) as in the present invention, the heat generated from the CPU (10) is not accumulated inside the main body, so the cooling efficiency is improved. In addition, if all of the heat generated from the CPU (10) is discharged to the outside directly through the blower pipe (130), the temperature inside the main body does not rise significantly, so there is no need to increase the capacity of the ventilation fan for ventilating the inside of the main body, and if the capacity of the ventilation fan is small, the amount of dust flowing into the inside of the main body also decreases.

[0048]

[0049] The blower pipe (130) according to the present invention is provided with an insulating function so that the heat inside is not transmitted to the outer surface, thereby preventing the surrounding air from being heated by the blower pipe (130).

[0050] The insulation function can be applied to various known functions. For example, insulation layers can be provided on the inner and outer sides of the blower pipe (130), or the blower pipe (130) can be made of a double structure with an insulation layer on the inner side. In addition, if necessary, the material of the blower pipe (130) can be made of a material with low thermal conductivity. However, in a preferred embodiment of the present invention, the blower pipe (130) can be configured to be composed of an inner wall (133) and an outer wall (135) so that an isolated vacuum layer (137) is formed between the inner wall (133) and the outer wall (135). In addition to this, it goes without saying that various known insulation functions that can prevent heat flowing inside the blower pipe (130) from being transferred to the outside (inside the main body) can be applied.

[0051]

[0052] The computer CPU cooling system according to the present invention may be equipped with a blower fan (150) in the blower pipe (130). The blower fan (150) may be equipped with various types of known blowers in various locations as long as it can transfer air inside the blower pipe (130) from one side to the other side. Generally, the cooling unit (100) facing one end of the blower pipe (130) is equipped with a heat dissipation fin (110) and a cooling fan (115) for cooling the heat dissipation fin (110). In this case, the computer CPU cooling system according to the present invention may be configured so that the cooling fan (115) for cooling the heat dissipation fin (110) transfers air in the direction of the blower pipe (130), so that the cooling fan (115) functions as the blower fan (150).

[0053] In addition, if necessary, a separate blower fan (150) may be provided on the other side of the blower pipe (130) or on the main body case (30) facing the other side of the blower pipe (130) separately from the cooling fan (115) as shown in the drawing (see FIG. 2). Thus, the heat generated while cooling the CPU (10) can be transferred to the blower pipe (130) and quickly released to the outside. In addition, one end of the blower pipe (130) may be configured to be spaced apart from the cooling unit (100) by a certain distance so that the surrounding air is supplied to the cooling unit (100) through the spaced apart space.

[0054]

[0055] The cooling unit (100) of the computer CPU cooling system according to the present invention may be a water-cooled cooling unit (100) configured such that one side faces the CPU (10) and the other side is provided with heat dissipation fins (110), and a coolant pipe (170) passes between the heat dissipation fins (110). At this time, a part of the coolant pipe (170) may be configured to be arranged along the longitudinal direction of the outer surface of the blower pipe (130). That is, the coolant pipe (170) may be provided in a spiral shape while wrapping around the longitudinal direction of the blower pipe (130), or may be arranged in a circumferential direction while reciprocating along the longitudinal direction of the blower pipe (130).

[0056] In general, water cooling is more efficient than air cooling in cooling systems. For this reason, water cooling was sometimes applied to conventional computers to cool the CPU (10). Water cooling is a method in which refrigerant or water flows inside a refrigerant pipe (170) to cool the heat of the CPU (10). The longer the refrigerant pipe (170), the greater the cooling time and surface area, thus improving efficiency. However, the reality is that there is not enough space inside the computer body to install a refrigerant pipe (170) of sufficient length. However, since the computer CPU cooling system according to the present invention can be installed by wrapping the refrigerant pipe (170) around the outside of the blower pipe (130), a refrigerant pipe (170) of sufficient length can be installed, and there is an advantage in that the cooling efficiency can be further improved when the water cooling unit (100) is applied together with the blower pipe (130). And since the blower pipe (130) is equipped with an insulating function as described above, the heat inside is not transferred to the external refrigerant pipe (170).

[0057] The heat emitted from the refrigerant pipe (170) provided on the outside of the blower pipe (130) will not be emitted to the outside of the main body through the blower pipe (130) but will be emitted to the inside of the main body. However, since most of the heat is emitted to the outside through the blower pipe (130) and the heat emitted through the refrigerant pipe (170) is relatively small, the temperature inside the computer main body does not rise significantly. In addition, since the computer to which the computer CPU cooling system according to the present invention is applied has a ventilation fan provided in the main body case (30) like a conventional general computer, the heat emitted through the refrigerant pipe (170) can be sufficiently discharged through the ventilation fan.

[0058] In one embodiment of the present invention, a heat dissipation fin may be provided on the outside of the blower pipe (130) at a position that does not overlap with the position where the refrigerant pipe (170) is arranged. Thus, the heat emitted from the refrigerant pipe (170) may be transferred to the heat dissipation fin (110) through the outer wall of the blower pipe (130) or may be directly transferred to the heat dissipation fin (110) to be cooled.

[0059] Meanwhile, the aforementioned refrigerant pipe (170) may be disposed along the length of the inner surface of the blower pipe (130) rather than the outer surface of the blower pipe (130). Thus, the heat released from the refrigerant pipe (170) may also be released to the outside through the blower pipe (130). However, although the above structure may be efficient when the amount of heat released from the cooling unit (100) is relatively small, when the amount of heat released is large, the refrigerant pipe (170) may be heated by the heat passing through the blower pipe (130), thereby lowering the cooling efficiency. Therefore, when the amount of heat released from the cooling unit (100) is large, it is effective to distribute the refrigerant pipe (170) on the outer surface rather than the inner surface of the blower pipe (130).

[0061] FIG. 5 is a drawing showing a state in which a CPU cooling system for a computer according to another embodiment of the present invention is mounted on a computer body, FIG. 6 is a cross-sectional view showing the structure of a blower pipe and cooling fins according to another embodiment of the present invention, and FIG. 7 is an exploded perspective view of a CPU cooling system for a computer according to another embodiment of the present invention.

[0062] Referring to FIGS. 5 to 7, a computer CPU cooling system according to another embodiment of the present invention is equipped with a blower unit (170) that blows air to a cooling unit (100).

[0063] The blow unit (170) is configured such that the blow fan (171), the cyclone (173), and the nozzle (175) are connected to each other. The blow fan (171) sucks in surrounding air and supplies it to the cyclone (173), and the cyclone (173) is configured such that its cross-sectional area becomes narrower as it moves in the direction of air transport, so that it compresses the supplied air and then supplies it to the nozzle (175), and the nozzle (175) is configured such that the spraying direction is toward the CPU (10) and / or the cooling unit (100), so that the compressed air supplied from the cyclone (173) is sprayed to the CPU (10) or the cooling unit (100).

[0064] The blow unit (170) prevents water droplets from condensing on the CPU (10) and the cooling unit (100) while cooling the CPU (10) and the cooling unit (100). As will be described later, the cooling unit (100) according to the present invention can apply a Peltier element (113) to the cooling unit (100). In many cases, the temperature of the heat absorption unit of the Peltier element (113) is lowered, causing water droplets to condense on the surface. The blow unit (170) can improve cooling efficiency by blowing a strong wind on the cooling unit (100) to which the Peltier element (113) is applied, and can also prevent water droplets from condensing on the cooling unit (100).

[0065] The configurations not described in FIGS. 5 to 7 are the same as those in FIGS. 1 to 4.

[0066]

[0067] FIG. 8 is an exploded perspective view of a blower pipe according to another embodiment of the present invention, and FIG. 9 is a cross-sectional view of a blower pipe according to another embodiment of the present invention.

[0068] Referring to FIGS. 8 and 9, a blower (130) according to another embodiment of the present invention is provided with a Peltier element (113) configured so that the heat absorption portion (low temperature portion) of the cooling portion (100) faces the CPU, and a cooling fin (110) provided on the heat dissipation portion (high temperature portion) of the Peltier element (113).

[0069] The Peltier element (113) has a configuration that has been used in some computer CPU cooling applications. The Peltier element (113) functions by having one side as a heat absorber and the other side as a heat dissipator, absorbing heat from one side and dissipating it to the other side. The Peltier element (113) is a known configuration, and thus a detailed description thereof will be omitted.

[0070] According to another embodiment of the present invention, a blower tube (130) is provided with cooling fins (110) on the other side from which heat is released from the Peltier element (113), and the cooling fins (110) may be configured to extend long in the other direction from the inside of the blower tube (130). Cooling fins of this structure may also be applied to the embodiments of FIGS. 1 to 4 described above.

[0071]

[0072] Meanwhile, it is a well-known fact that applying a Peltier element (113) to a cooling unit (130) improves cooling efficiency, but when water droplets condense on the heat-absorbing unit (low-temperature unit) of the Peltier element (113), not only does the cooling efficiency decrease, but problems such as short-circuiting may also occur in the surrounding terminals.

[0073] Therefore, when applying the pelletizer element (113) to the cooling unit (130), it is preferable to also provide the blower unit (170) of FIGS. 5 to 7 so that the compressed air discharged through the nozzle (175) of the blower unit (170) blows the pelletizer element (113) and its surroundings to prevent water droplets from condensing.

[0074] The configurations not described in FIGS. 8 and 9 are identical to the configurations described above.

[0078] While the detailed description of the present invention has described specific embodiments, it is clear that various modifications are possible without departing from the scope of the present invention.
